Reversible Plough Part Differences for Sandy and Clay Soils

The same plough works very differently in sand and in clay. The soil decides which parts wear fastest, how the body should be set, and which materials give the longest service. Matching parts to the local soil is a quiet way to extend component life and keep the finish clean.

How sand wears the plough

Sandy soil is highly abrasive. It scours the share edge, the mouldboard face and the coulter, rounding edges within hours of contact. In sand, harder, abrasion-resistant shares pay off, and they need replacing on a shorter cycle. Mouldboards wear slowly at first but develop a polished, pitted surface that increases drag over time.

How clay wears the plough

Clay sticks rather than scours. It adheres to the mouldboard face, builds up at the joint, and pulls harder as the surface roughens. In clay, a smooth mouldboard surface matters more than raw hardness, and shares need a sharp edge rather than the hardest possible tip. Damp clay also keeps seals and pins damp, so corrosion protection matters more.

Choose shares for the soil

For sandy ground, select shares with a treated, abrasion-resistant edge and expect shorter replacement intervals. For clay, choose a share that slices cleanly and keep it sharp, because a blunt share smears clay into a compacted crust. Either way, fit shares as matched sets so the whole plough penetrates evenly.

Mouldboards and finishing

In clay, a mouldboard with a smooth, slightly polished surface sheds soil best. Keep the face clean after work, and touch up any rust that catches on clay. In sand, watch for pitting on the mouldboard, which increases drag even though the surface still looks smooth. Replace or refurbish pitted mouldboards before fuel use climbs.

Tailor the whole set to the field

A plough that moves between sandy and clay fields benefits from adjustable setup: share type, working depth and body angle can be tuned per field. Keep notes on what works in each soil type, and stock the wear parts that the local ground consumes fastest. The right parts, matched to the soil, keep the plough working longer and the finish cleaner.
